9. A student using a diffraction grating ruled with 6.20 x 104 lines/m to measure the frequency of some monochromatic light. If the nodal lines are 0.0522 m apart at a distance of 1.50 m from the grating, what is the frequency of the light used? (5.3 x 1014 Hz) 10. Using the information in question 9, determine the distance between nodal lines if the grating was changed to 9.30 x 104 lines/m while all other variables remained unchanged. (0.0783...
